Abstract
Repeated GPS surveys in North China provide a direct measurement of current crustal motions. GPS surveys have been carried out in this region in 1992, 1995,and 1996 respectively. The horizontal crustal deformation and tectonic activity have been studied using GPS measurements The GPS velocity fields are estimated and they are used to estimate the North China sub-plate and its intrablock rotation motions. The sub-plate and blocks present some rigid features. Sub-plate and blocks rotations are discussed in details by the study of GPS measurements, geology structural, and seismicity and paleomagnetic measurement. The Euler model using GPS data agrees with NNR-NIUVEL-1A model. The current rotation pattern of Eerduosi block, Taihang block, Jiluxi block and Jiaoliao block all rotate in counterclockwise in ITRF96 frame. Yinyan block relative to Eerduosi block, Yinyan block relative to Taihang Jiluxi block, and Eerduosi block relative to Taihang Jiluxi block all have extension trend. Finally, the dynamics of rotation is preliminarily studied It is associated with the collision of India, Pacific with Eurasia.
